Issue with Walmart Onn. 4k streaming box keeping HDR enabled even after I disabled it

by beanburgers578

The Walmart Onn. 4k streaming box I am currently using keeps HDR enabled after I explicitly disabled it in the device settings (the device is up to date on Version 10, Firmware Version 1.01.36). I want to disable HDR because it keeps making media I play on the device very dark. I tried using Youtube but HDR was still enabled for videos even after I disabled it (there are no HDR options in the Youtube app settings but I disabled it in the device settings before I started playing the video). I then tried using SmartTubeNext (open source Youtube client for androidTV devices) and I set a resolution preset in the settings to not use HDR but when I played videos in the app HDR was still enabled. The TV I am using does not have HDR built into it and it doesn't have any auto dimming feature. Is there any way to actually disable HDR on my device?

The temporary solution:

I believe a temporary solution to this issue would be to turn the HDR option on, exit the HDR menu, go back to the HDR menu, and then turn the HDR option off (or if HDR was already enabled then turn it off, exit the menu, turn it on, exit the menu, and turn it off). I did the following steps and it seems HDR was turned off for me. Since this issue was most likely caused by a bug the HDR option might eventually turn on when you restart the device.

Turn HDR from auto to off on your TV, there is definitely an option.

If HDR is turned off and it's not off I don't know what else you can do. I leave mine on auto on my 1080p TV Apps should see that is off and not present HDR content. Apps should also see that your TV isn't HDR. Maybe tere is a bug on non HDR 4k TV's. I don't have one to test that theory with. Have you tried with auto instead of off?

I am having the same issue on the 2 ONN devices I have. HDR is turned off and certain shows on Prime and Netflix are unwatchable. The Terminal List on Prime is one example. On Netflix the last season of Ozark and The Sandman are just too dark to watch. There are members on the AVSForums that are complaining of the same issue. One member has done some in depth tests and stated the ONN device sends an HDR signal even when HDR is set to off on the ONN device. I honestly think a fix has to come from ONN. In the meantime I just use my Samsung TV apps when I want to watch those shows. Then use the ONN for other shows.
